I replaced my 25+ year old "rat trap" steel and leather toe clips with these. They were originally on a road bike and I switched to a mountain bike since over the years the roads in my community have deteriorated to the point of unsafe for thin tires. As shoe styles changed over the years the toe straps became less desirable since the cleated soles of so many athletic shoes won't pull out as readily if needed. These mini clips hold the toe in just enough to exert on the upward stroke for efficiency but if needed, one can pull the feet out quickly. I question how long they might last since they are plastic. Haven't had them long and have put maybe three hours of riding on them. The hardware that was included probably should have included a different size washer for a better fit. I have them mounted on my old Diamonback with its original pedals. They work as well as I expected--I'm please with them.

Got these for my wife, and mounted on her Mountain Bike. She is a casual cyclist and doesn't feel comfortable "clipped-in". Helps her keep foot in the right position and helps her from foot slipping off pedal. Easy in/out of pedal, mounts easily. Lightweight.

Diamondback bike has a 45 degree slope to edge of pedal. Toe clips need 90 degree edge. No where in description does it mention it may not work on all bikes. These are sitting in my garage now because return shipping will nearly cancel refund.
